Specification of Letters Patent.

Application filed September 25, 1913.

Patented Sept. 15, 1914. Serial No. 791,767.

To all whom it may concern Be it known that 1, COLUMBUS HoUcK BISHOP, acitizen of the United States, and a resident of El Reno, county ofCanadian, and State of Oklahoma, have made certain new and usefulImprovements in Car-Gear Equipments, of which the following is a.

pling head, and'having mechanism for en' gaging the bra-ke mechanism ofthe adjacent ltruck for applying the brakes, when the coupling bar ismoved inward, and wherein spring mechanism is provided for normallypressing the coupling bars outward.

A further object is to provide mechanism in connection with the couplingbars, for locking the brakes in set position.

In the drawings: Figure 1 is a top plan View of the base frame of theequipment, Fig. 2 is a side view of the same, igs. 3 and 5 are sectionson the lines 3 3 and 5-,-5 respectively, of Fig. 1, Fig. 5 looking inthe direction of the arrows, with parts broken away in Fig. 5. Fig. 4 isa perspective view of one of the couplings. Fig. 6 is a section on theline 6-6 of Fig. 1, looking in the dil rection of the arrow, and Fig. 7is a top plan view of the locking mechanism for holding the brakejin setor released position. rl`he present embodiment of the invention consistsof a substantially rectangular open base frame, composed oflongitudinally eX- tending side members 1 and connecting end members 2,eachl of the said members being of channel material, as shown in Figs Band 5, and arranged with its channel inward. Intermediate the connectingend members, the side members are connected by cross bars 8 on each sideof the transverse center of the frame, and by other crossbars 4Ladjacent to the end members 2, and by other cross bars 5 adjacent to thecross bars 3.

Oppositely arranged pairs of diagonal braces 6 are arranged between theadjacent cross bars 3 and 5, the pairs of braces `being crossed, and oneof the pairs being arranged on each side of the longitudinal center ofthe frame. |The bars 3 are connected by cross plates 7 on each side ofthe longitudi# nal center of the frame.

4 The cross plates 7 are arranged in pairs, the members of each pairbeing parallel and spaced apart vertically from each other. rlhe uppermember of each pair has its ends resting upon the upper edges of thecross bars 3, and secured to the said cross bars, while thelower memberof each pair is provided at each of its ends with an angular lug 10, forengaging the inner face of the adjacent cross bar, and the lugs areconnected to the cross bars by means of rivets or bolts. A bolster 11 isarranged transversely of the frame between each pair of the cross plates8. r

A pair of elliptical springs 12 is arranged each spring being transverseto the frame. TheA adjacent halves or sections of the springs areconnected by a coupling 13, and the outer face of the other section orhalf of each spring is adjacent to one of the cross bars 3, and isconnected to a cross head or shoe 14 on the adjacent end of the adjacentcoupling bar 15. The shoe 14e of each coupling bar is curved on the faceadjacent to the spring to lit the outer face of. the adjacent leaf, andeach shoe is provided with openings 16 near4 its ends for receivingbolts or rivets, to connect the shoe to the spring.

Each coupling bar 15 slides through a bearing 17 on the upper face ofthe adjacent bolster, and each. coupling `has connectedl thereto anarc-shaped cross bar 18, the said bar being on the inner side of theinner.

cross plate of the adjacent pair, and each cross bar is connected to thecoupling bar by an arm 19. The cross bars 18 are arranged with theirconvex surfaces inwardly, and each of the said cross bars is designed tooperate the brake ofthe adjacent truck, when .the coupling bar ispressed inwardly. The coupling for the car is connected with the outerend of thecouplin bar, and the said coupling may be of any esiredcharacter or make. The trucks are pivoted to the car body in a manner tobe later described, and the arched form of the cross bar 18 is to permitthe cross bar to engage the operating'lever regardless of the relativep'o'- sition of the truck and the body.

The wheels 20 are secured to the axles' 21 in the usual manner, and thesaid axles are journaled in bearing blocks 22 which are movablevertically in journal boxes 23, 'The journal boxes are on both sides ofthe wheels 20,'as shown in Fig. 5, and the said -boXes pedestals of eachtruck near the ends thereof, and the holsters 11- of the-base frame arepivoted to the trucks constituted by the pedestals' and theirconnections in the usual manner, andlduring the Iturning of the trucksvthe bolstersrmove upon the girders 9 before mentioned; The holsters 11are transversely grooved on their under faces and near their ends asindicated at 11EL to receive the girders. lTwo brake shoes 26 and 27respectively are arranged adjacent to each of the inner wheels of eachtruck, the-said shoes being on opposite sides of the wheel. Two shoes 28and 29 respectively are arranged adjacent to each ofthe outer wheels ofeach truck.

The shoes 28 at the outer sides ofthe trucks are connected to theends'of a rod 28'. The rod is supported by a lever 29 the lower end ofthe lever engaglng the ro at approximately its center, and the upper endof the lever is pivoted to a bracket arm` 30 extending 'outwardl fromthe adjacent edestal on the truck. ach of the yshoes 29 1sA connected toone end of a rod 29, and e'achrod is supported by a lever 31, the lowerend of the lever being connected to the rod at approximately -itscenter. Each lever 31 is pivoted intermediate its ends to an arm 32extendingeinwardly from 4the outer pedestal of the truck. H

The shoes 26'are arranged on the ends of i a rod 26, and a lever 33 isconnected to the rod intermediate its ends. The upper end of the lever33 is pivoted -to a bracket arm 34 .extending fromthe inner pedestal ofthe truck. The brake shoes 27 are connected to 'the ends of a rod 27,and a lever 35 engages the rod at its lower end, a'nd at approximatelythe center of the rod. The ,upper end of' the lever 35 is position forengagement by the cross bar 18 of the adjacent coupling bar 15, and alink 36 connects the lever 35 with the upper end of the lever 31.

A link 37 ispivoted at one end to the lever 35 adjacent to 'theconnection of the link 36, and the said link 36 is pivoted at itsopposite end to the lever: 29 intermediate the ends of the said lever.The link 37 is also pivoted to the lever 33 intermediate the ends of thesaid lever, and it will be obvious that when the upper end. of the lever35 is' 'moved inwardly, the eight shoes of the truck will be applied tothe wheels. Eachof the "coupling 'bars 15 slides in mortises 38 and 39in the cross bars 3 and 5 at the said end, and y@ach of the said bars isprovided with oppositely extending lugs 40 adjacent to the mortises'38,the said lugs being adapted to engage the outer side of the cross bar tolinut the inward movement of the coupling bar, and the other pairs oflugs 41 and 42 are arranged on the couplin bar 3, for engaging the saidbar, to limit Vthe movement of the coupling bar in 'each direction,

It will be evident that when either of the coupling bars is movedinwardly to compress the springs 12, the brakes at that end of the caradjacent to the coupling bar will be set. The springs 12 cannot'swinglaterally on account of theguide plates 7, and when either coupling bar1s pressed inwardly, the springs will becompressed. Mechanism is alsoprovided for coperating with thelug 41 and 42 at one side of eachcoupling bar for holding the brakes operated by Vthe said bar in set orreleased position.' The said mechanism comprises a pair of blocks 43 and43* respectively', the said blocks being of a width such that they willbe received between a lug or shoulder 41 and the adjacent cross bar 5.'-Each block is carried on the end of a slide od 44, and each rod ismounted to slide in earings 45 on one of the cross bars 5. At its outerend each rod is bent laterally from the cross bar, as shown at l46, andthe free end of each of the angular portions is provided with verticallyspaced lugs 47. A lever 48 ispivoted in a slot 50 in the cross bai` 5,by; means of a pivot pin 51, and the said levereis slotted at each ofits ends, as indicated at' 49. A bolt 52 is passed through each lug andthe adjacent slot, for ivotally connecting the angular portion thelever. y l A In operation, the coupling heads are connected with theouter ends of the coupling bars 15, and it will be evident that when theof t e rod to said coupling` bars are pressed inwardly, the

brakes of the trucks adjacent to the bar will be set. As soon as thepressure is released, the springs 12 will expand, releasing the brakes.When itis desired to fix the brakes in either open or closed position,the lever 48 adjacent to the coupling bar is operated to move one of theblocks 43 and`43, as the casemay be, inwardly, as shown in Fig. 7.

The lever 48 may be operated in any suitable manner, each lever havingopenings 53 at Iits ends for connection with suitable operatingmechanism. When the coupling bar is pressed inwardly, the block 43' willlit between one of the shoulders 41 and the cross bar 5, and Ywill holdthe coupling bard with the brake set. When the brakes are released, andthe coupling bar is 1n its outermost ponimeer sition, the block 43 maybe moving inwardly to a position between the shoulder 42 and the crossbar 5,.
